On a lot at New York's John F. Kennedy Airport sits a long-abandoned, perfectly preserved airline terminal — though it may be unrecognizable as a place for passengers to kill time today. The Trans World Airlines (TWA) Flight Center's sleek, neo-futuristic design makes it look more like an airport from "The Jetsons."

Most airports funnel passengers into the middle, away from "the light and any sense of exterior orientation," writes architecture critic Alexandra Lange.

"It's the opposite at TWA," Lange says, "the perimeter is for humans."

It was PACKED at today's #OHNY tour of the TWA Flight Center at JFK Airport, Eero Saarinen's swooping architectural masterpiece, as people crowded in for their last chance to see the curvaceous gem before it becomes the TWA Flight Center *Hotel.* ✈️🕟💺 #ohnywknd #ThisPlaceMatters
